1.Difference of nature:
Most of the resin powder contains solvents such as dibutyl phthalate or benzyl benzoate, which are absorbed by materials with high oil absorption values such as superfine heavy calcium powder, kaolin, and talc powder, and are mixed with some water-reducing It is a resin powder compounded with solvent and polyvinyl alcohol.It is a product of solvent compounding, which is toxic and will endanger people's health.
Redispersible polymer powder is a water-soluble redispersible powder with fluidity on the hand. It is a copolymer of ethylene and vinyl acetate, and a water-soluble product with polyvinyl alcohol as a protective colloid. It is a water-soluble and environmentally friendly product that meets national standards.
2. Appearance of Redispersible polymer powder and resin powder:
Resin powder
Resin powder has no fluidity on the hand, It is not a free-flowing powder and builds up in lumps.
Redispersible polymer powder
Redispersible polymer powder is evenly distributed and piled up with free flow.
3. Characteristics of redispersible polymer powder and resin powder：
Resin Powder
There are different colors, some are white. If you add pigments of various colors, corresponding colors will appear.
The amount of addition is very small. The amount of addition for one ton is about 5kg-12kg.
The early strength of the mortar is good, and the strength of the cement has not fully increased in three days, and the Resin rubber powder has already corroded the insulation board and damaged it.
Use resin powder as mortar to bond XPS board without interface agent, mainly because the solvent in the resin powder will corrode the insulation core material, so as to achieve the purpose of breaking the board.
Redispersible polymer powder
Redispersible polymer powder has film-forming properties. 50% aqueous solution forms an emulsion, which forms a plastic-like film after 24 hours on the glass. The formed film has certain flexibility and water resistance.
Redispersible polymer powder has a high binding capacity. Good bonding strength makes the mortar have excellent alkali resistance and water resistance, which can improve the tensile strength and flexural strength of the mortar, and improve the wear resistance of the mortar.
It has strong flexibility in the anti-cracking mortar, ensuring that the insulation core material can ensure the adhesion between the mortar and the insulation core material under the environment of temperature changes (thermal expansion and contraction), and will not cause the mortar to separate from the insulation core material , Bonding and so on.
