Adhesives & Emulsions

JOYFORCE Polyvinyl Alcohol has allowed for its widespread use in industrial adhesives, she understands and continues to develop specialty and unique grades for the adhesives market. From ceramic binders to adhering to substrates like paper and wood, keeps improving tensile adhesive strength as a sole adhesive or as an additive. And can be use in polyvinyl acetate emulsions, specifically in wood and paper adhesives, water-resistant wood adhesives, general-purpose adhesives such as textile, leather, wood, and porous ceramic surfaces. The partially hydrolyzed grades are often selected for remoistening adhesives.

 

Polyvinyl alcohol also has a very low surface tension and the ability to disperse into very fine particles in water, and is used to produce polyvinyl alcohol emulsions. It is also a very good protective colloid, which makes polymerized, colloidal and granular polyvinyl alcohol form a stable aqueous emulsion to prevent its coagulation or degradation. Choosing from various PVA products depends on their performance. For latex with strong cohesive force at the initial stage of production, fully alcoholysis type PVA can be selected, such as marked PVA 1799, PVA 2099 and PVA 2499; on the contrary, when producing low-viscosity latex with high solid content, PVA with low polymerization degree can be combined with PVA with high alcoholysis degree is used in combination, PVA 0388 and PVA 1799 are used together.

As an additive for cement and mortar, PVA can effectively increase the adhesion and fluidity of cement and mortar, slow down the drying time of the cement surface, increase coating adaptability and prevent the cement cloth surface from cracking. It is suitable for wall, ceiling whitewashing and tile bonding thanks to its simple application method with desired effects.

 

PVA can also be used as an adhesive for forming boards, such as: gypsum prefabricated boards, sound-absorbing boards, etc., whether it is organic fiber (cane bagasse, wood chips) or inorganic materials, it can be equipped with PVA's high-efficiency adhesion and water resistance characteristics to make it compression and bonding into a sheet. PVA also has good uses in coatings. PVA aqueous solution is catalyzed by hydrochloric acid and formaldehyde is condensed to form a water-resistant PVA formal polymer compound, which is widely used as interior and exterior wall coatings, finishing, caulking, etc. of buildings. PVA coating has good weather resistance, water resistance, does not swell when exposed to water, does not embrittle, is non-toxic, tasteless, and has the advantages of low price. In this field, the traditional varieties can only be used in the manufacture of forming plates. In the coating field, PVA with a higher degree of polymerization.
