Q
Relationship and Application of PVA Glue and Latex Glue
1. PVA can be used as one of the ingredients in latex glue to enhance bonding performance and water resistance.
2. Latex glue usually refers to PVAc emulsion, but some latex glues on the market may contain PVA ingredients, so sometimes they are confused.
3. In different application scenarios, the two can be used interchangeably, but the performance will be different.
