“…Similarly, Misman et al (2018) found that modification on either micro or nanostructure of starch effectively responds to the increment of the mechanical properties of NRL-based adhesives. Akbari et al (2014) concluded that adding an equal amount of modified rice starch with NRL improved the thermal stability, which technically means starch can act as a perfect binder to NRL, and this combination can be an alternative to synthetic adhesives for the manufacturing of wood composites. The chemically modified starch filler enhanced the mechanical properties of NRLbased composites in terms of internal bonding and shear strength.…”

The use of formaldehyde-based synthetic adhesives for the development of wood-based panels has increased rapidly in the industry. Synthetic adhesives are regarded as a threat to human health and a pollutant because they emit formaldehyde's carcinogenic gas. The breakthrough has prompted to seek for a long-term solution to the formaldehyde threat with natural resources. There has been a significant rise in bio-based adhesive technology and development in the wood-based panel industry. The current review article is intended to present the potentials and the drawbacks of the development of bio-adhesives from sustainable resources such as natural rubber latex (NRL) and starch. This review also discussed the chemical modification and crosslinkers of starch to improve water resistance and adhesion properties. Moreover, this article discusses the compatibility of modified rice starch and NRL for their conclusive applications as wood-based panels adhesive. The findings suggested that bio-based adhesives could replace more synthetic-based adhesives with comparable performance in the near future.

“…This was probably due to pure starch-based adhesives do not give good performance in strength and bonding between veneers and starch-based adhesive. According to Akbari et al [5], the same testing was used for medium density fiberboard where there was no increment in loading at higher starch content due to lowest composition of natural rubber latex in the starch-based adhesive. Hence, pure starch-based adhesive has no ability to resist the loading strength except adding natural latex which tends to reduce brittle failure of the blend [6].…”

Abstract.Recently, starch has attracted great consideration as a raw material on wood adhesives in the wood industry. Cassava and sago starchbased adhesive are renewable, biodegradable and environmental friendly product when compared with other petroleum-based adhesives. In this study, different starches-based adhesive has been produced. Mechanical properties of plywood made from Acacia mangium veneers with different starches-based adhesives (cassava and sago) as binder cured at different curing temperatures (100 o C, 120 o C and 140 o C) has been determined. All materials (starch, vinegar, water and glycerol) were cooked and stirred until the mixture reached 70 o C -80 o C which become sticky and whitish. After that, starch-based adhesives were applied on the veneers by using spreader, and the plywood were pre-pressed for 30 minutes with 20 kg load before hot-press. Cassava starch-based adhesive showed the highest Modulus of Elasticity which was 12410.56 N/mm² than sago starch-based adhesive, while Modulus of Rupture of the cassava starch-based adhesive at 100 o C showed highest mean value at 74.19 N/mm². Sago-starch based adhesive at 140 o C showed the highest shear strength with 1.11 N/mm². In short, cassava and sago starch-based adhesives gave good performance in mechanical properties such as bending for pressed temperature (100 o C and 120 o C), and shear at 140 o C pressed temperature.

“…The study was aimed on increasing the mechanical and physical properties of MDF by using NR latex and starch as an adhesive. The results of this study indicated that starch can be used as a viable alternative binder with NR latex [90]. Starch-grafted-polyvinyl acetate (starch-g-PVAc) and epoxy resin can be used as high cohesive energy component to improve the dry shear strength of the starch adhesive [91].…”

Increasing global energy crisis and scarcity of petroleum resources has shifted focus of chemical industries to look for alternative raw material resources. The main focus of raw materials in wood adhesives, such as petroleum and natural gas [1] [2], would be gradually replaced by renewable biopolymers. Starch is a relatively inexpensive and renewable product from abundant plants, easy processing and it has been extensively used as binders, sizing materials, glues and pastes [3], but its bonding capacity is not strong enough to glue wood [4]. Extensive research has been carried out on improving the cohesive properties, especially water resistance, of starch-based adhesives. In starch-based wood adhesive many new approaches have come forward for effective use it in wood/wood composite adhesive giving comparable performance as synthetic adhesives. This review of starch-based adhesives is made with the focus on starch modification methods for improving properties of starch-based adhesives.
