“…The level of reactivity of the phenolic compounds contained in mangium bark extract to formaldehyde is expressed by the Stiasny number. The Stiasny number indicates the reactivity of the tannin compound contained, and a number reaching one hundred (100) suggests that the tannin extract contains polyphenols which are very reactive in the polymerization process [ 42 ]. The Stiasny number of the tannin obtained in this study was 73.17%.…”

The use of alternative raw materials, such as agricultural biomass and by-products, in particleboard (PB) production is a viable approach to address the growing global demand for sustainable wood-based materials. The purpose of this study was to investigate the effect of the type of hardener and tannin-glyoxal (TG) adhesive formulation on the cohesion and adhesion performance of TG adhesives for areca-based PB. Two types of hardeners were used, NH4Cl and NaOH, and three adhesive formulations with tannin:glyoxal ratios (i.e., F1 (1:2), F2 (1:1), and F3 (2:1)) were applied to improve the cohesion performance and adhesion for areca-based TG adhesive for PB. The basic, chemical, and mechanical properties of the TG adhesive were investigated using a Fourier transform infrared spectrometer, rotational rheometer, dynamic mechanical analyzer (DMA), and X-ray diffractometer. The results show that a high glyoxal percentage increases the percentage of crystallinity in the adhesive. This shows that the increase in glyoxal is able to form better polymer bonds. DMA analysis shows that the adhesive is elastic and the use of NH4Cl hardener has better mechanical properties in thermodynamic changes than the adhesive using NaOH hardener. Finally, the adhesion performance of the TG adhesives on various types of hardeners and adhesive formulations was evaluated on areca-based PB panels. Regardless of the type of hardener, the TG adhesive made with F1 had better cohesion and adhesion properties compared to F2 and F3. Combining F1 with NH4Cl produced areca-based PB panels with better physical and mechanical qualities than the adhesive formulations F2 and F3, and complied with Type 8 particleboard according to SNI 03-2105-2006 standard.

“…The solids content indicates the resin content contained in the adhesive; the value tends to be directly proportional to the viscosity, specific gravity, and gelation time. The high resin content causes the viscosity and specific gravity of the adhesive to be high, whereas the gelation time tends to be longer [17]. Adhesives with a high solids content will have high adhesion.…”

Phenol-formaldehyde (PF) resin is one of the most well-known adhesives for exterior use. PF adhesive is one of the commercial thermoset polymers that is used extensively due to its many benefits. This study investigated the influence of different types and levels of catalysts, i.e., NaOH and CaCO3 at 1% and 5% based on the solids content of PF resin on the adhesive properties, adhesion, and cohesion strength of PF resin. The results show that the catalyst type significantly influenced the PF adhesive viscosity and pH. Furthermore, the catalyst level significantly affected the PF adhesive’s solids content, viscosity, and gelation time. The cohesion strength of PF-CaCO3-1% was more significant than the PF control at 75 °C. According to the DMA analysis, the mixed PF-NaOH-5% provided the highest storage modulus, followed by the PF-CaCO3-1%, with values that were not statistically different from one another. The adhesion strength of PF-CaCO3-1% was the highest, whereas the adhesion strength of the PF control was the lowest, as confirmed by the cohesion strength. According to the findings, adding CaCO3-1% as a catalyst of PF resin would result in better adhesive adhesion and cohesion properties for wood composites in the future.

“…The engineered rattan product made in this study was in the form of a 3-inch rattan laminated board measuring 60 cm x 7.5 cm x 1.5 cm in length, width, and thickness, respectively, using 4 types of synthesized adhesive types of natural resources and 2 types of commercial synthetic adhesives, while on a pilot scale at PIRNAS the rattan laminated panel has the dimension measuring 400 cm x 60 cm x 6 cm, and produced using a commercial synthetic adhesive type from the resorcinol group commonly used in the wood processing industry (Pari et al, 2019). In this research we applied 3 kinds of glue spread rates on the surface, namely 150, 200, and 250 g/m 2 .…”

“…Nevertheless rattan with large diameter can further developed into composite products in the form of Rattan Laminated Board (RLB) with the desired dimensions from rattan strips with the aid of appropriate adhesives. Studies on the manufacture of rattan laminated boards have been done by using water based polymerisocyanate (WBPI) adhesive (Sulastiningsih, Trisatya, & Sukadaryati, 2019) and by using tannin-based adhesive (Pari, Abdurachman, & Santoso, 2019;Santoso & Pari, 2020). Studies on the pre-treatment of raw materials for the application of rattan laminate boards have not been widely carried out.…”

Rattan in Indonesia is traditionally utilized for furniture, binding materials, household appliances, and handicraft items. Small diameter rattans are commonly used by craftsmen, while large diameter rattans are not optimally utilized. Large diameter rattan, however, has potential to be developed into rattan laminated board (RLB) by gluing rattan strips using appropriate adhesive. Nevertheless, the information of the suitable natural adhesive for RLB production is still limited. Laboratory scale of RLBs with the dimensions of 60 cm x 7.5 cm x 1.5 cm were manufactured using batang rattan strips (Calamus zollingeri Becc.). The strips were glued with six types of adhesives (4 types of natural adhesives and 2 types of commercial synthetic adhesives) and three glue spread rates of (100, 150, and 200 g/m2) were used. The study objective was to determine the effect of rattan pre-treatments, adhesive types and glue spread rates on the bonding quality and formaldehyde emission of RLBs. The results showed that batang rattan can be processed into RLBs by using natural adhesives originating from wood bark extract (mangium, mahogany), merbau wood powder, as well as commercial synthetic adhesives such as isocyanate and polyurethane. The appropriate pre-treatment in producing RLBs for interior furniture was by applying oil heat treatment with kerosene solution (80 kerosene : 20 water) and glued with tannin adhesive of mangium bark extract with glue spread of 200 g/m2. Similarly, rattan strips treated with heated oil (80 kerosene : 20 water) and glued with polyurethane adhesive (glue spread of 200 g/m2) produced excellent RLBs for exterior furniture.
