RDP Ethylene Vinyl Acetate Copolymer Resin Powder Mortar Concrete Additive

Ethylene-vinyl Acetate Copolymer Resin Powder Industrial Grade Concrete Mortar Additive

JF REDISPERSIBLE POLYMER POWDER Product Introduce:

Redispersible latex powder products are water-soluble redispersible powders, which are divided into ethylene/vinyl acetate copolymer, vinyl acetate/vinyl tertiary carbonate copolymer, acrylic acid copolymer, etc., powder bonded after spray drying It uses polyvinyl alcohol as a protective colloid. This kind of powder can be quickly redispersed into emulsion after contact with water. Because redispersible latex powder has high bonding ability and unique properties, such as: water resistance, construction and heat insulation, etc., their The scope of application is extremely wide.

Precautions For Redispersible Latex Powder:

1. It is not advisable to put in the resin rubber powder at one time. It should be divided into several parts in order to find the right amount.
2. When polypropylene fiber needs to be added, it must be dispersed in cement first, because the fine particles of cement can eliminate the static electricity of the fiber, so that the polypropylene fiber can be dispersed.
3. Stir and mix evenly, but the mixing time should not be too long, 15 minutes is appropriate, long-term mixing of sand and cement is easy to precipitate and layer.

4. It is necessary to adjust the amount of additives and add HPMC in an appropriate amount according to the changes of the seasons.
5. Avoid damp and caking of additives or cement.
6. It is strictly forbidden to pile up and use with acidic substances.
7. It is forbidden to use it during construction below 5℃. Low-temperature construction will cause major engineering quality problems, causing the plastering mortar and the insulation board to not adhere. This is a later engineering quality problem without a remedial plan.

Redispersible Polymer Powder Functions:

1. The redispersible latex powder forms a film after being dispersed and acts as a second adhesive to play a strengthening role.
2. The protective colloid is absorbed by the mortar system (it will not be destroyed by water after film formation, or "secondary dispersion").
3. The film-forming polymer resin is distributed in the entire mortar system as a reinforcing material, thereby increasing the cohesion of the mortar.

Redispersible Polymer Powder Packaging And Storage:

It needs to be stored in a cool and dry place. The recommended period of use is six months. Please use it as early as possible when used in summer. If it is stored in a hot and humid place, it will increase the chance of agglomeration. Please use it once as much as possible after opening the bag. Otherwise, the bag opening must be sealed to avoid absorbing moisture from the air.
