Importance of fillers in the adhesive industry

Fillers are widely used in products of the polymer industry. Among the functions of fillers are price reduction, know-how control, improved processability, optical properties, thermal conductivity, control of thermal expansion, electrical properties, magnetic properties, fire delay and improved mechanical properties. Fillers are mostly used in polyvinyl chloride (PVC). In addition, they are also used in olefin polymers, nylons and polyesters. …

How to remove dried wood glue from wood?

The polymer base for the production of wood adhesive is polyvinyl acetate, which needs to be produced through emulsion polymerization of vinyl acetate monomer. This polymerization is done in two stages and discontinuously (batch) that in addition to monomer, potassium persulfate (as a initiator of polymerization), sodium bicarbonate (p-hash regulator), oxidized starch (colloid protector), Nonylphenyl polyethoxyethanol (emulsifier) ​​and water are …

A review of the factors of delayed curing_heating of epoxy resin

Epoxy resins are widely used in the composite, aerospace, building, electronics, adhesive and coating industries due to their physical and mechanical properties as well as good thermal, electrical and chemical resistance. Epoxy resins require chemicals called curing agents or curing agents for curing. These materials affect the processing conditions and the final properties of the resin system. In general, epoxy …
