Waterproof Glue Powder for Construction
- Product Information
Waterproof Glue Powder is a polymer modified adhesive powder specially developed for the construction industry, belonging to urea formaldehyde resin based functional materials. This powder is deeply crosslinked with hydrophobic groups and resin molecular chains through copolymerization reaction technology, forming a three-dimensional network structure and endowing it with excellent waterproof properties. The product presents white to light gray uniform granules with a neutral pH value, which can be safely applied to various building materials surfaces. Its essence is the dual action of physical adsorption and chemical cross-linking, which rapidly forms a dense adhesive film upon contact with water, effectively blocking the penetration of moisture.

Waterproof Glue Powder For Use:
1. Prepare a container, stirring tools, and 25kg of room temperature water (add the water twice).
2. Dissolving glue powder
First pour 15kg of water into the container,
then pour 25kg of resin powder into the water and stir to dissolve.
Stir into a paste until the glue powder does not agglomerate,
then add the remaining 10kg of water and fully stir to form a glue solution.
3. The mixed glue is used after 1 hour of waiting, and the effect is the best.
4. According to the production requirements of the product process, it can be mixed with additives such as curing agent(Ammonium chloride) .
5. During use, increase or decrease the ratio of resin powder to water according to the moisture content of the board and the local climate.
6. Amount of industrial flour added: 20-25% of the glue already blended.(190A to add)
Waterproof Glue Powder Features:
1. High bonding strength: This product has excellent bonding performance and can firmly bond various building materials such as stone, glass, metal, etc., ensuring the stability of the structure. Its adhesive strength can remain stable in both dry and humid environments, and can form a strong bond even underwater.
2. Excellent water resistance: Modified with melamine, this adhesive powder can maintain good bonding effect in humid environments and is suitable for building scenes that require waterproof treatment. It can solidify underwater and is suitable for underwater construction and long-term exposure to water environments.
3. Good adaptability: This adhesive powder can adapt to surfaces of different materials, providing reliable bonding even on smooth or complex structured materials. It can be used for bonding various building materials, including concrete, wood, metal, and plastic.
4. Strong durability: the product has good anti-aging performance, can maintain waterproof effect in long-term use, and reduce maintenance costs. It also has resistance to chemical corrosion and can maintain stability in acidic and alkaline environments.
5. Environmental friendliness: Through modification technology, the release of free formaldehyde has been reduced, which meets environmental standards and is suitable for indoor and outdoor building bonding applications. Its low VOC content and solvent-free formula make it safer and more environmentally friendly during construction.
Waterproof Glue Powder Application:
1. Adhesive bonding of decorative materials: used for bonding decorative materials such as tiles and stones, ensuring that the materials are firmly fixed and providing waterproof protection. It can adapt to decorative materials of different materials and provide stable bonding effect.
2. Ground waterproofing: Provide reliable waterproof protection in damp areas such as basements and bathrooms to prevent water vapor from rising. It can prevent damage to ground materials and extend the service life of the ground.
3. Roof waterproofing: Used for waterproofing treatment of roofs to prevent rainwater leakage and extend the service life of roofs. It can adapt to the complex structure of the roof and provide comprehensive waterproof protection.
4. Pipeline sealing: Provide waterproof sealing at pipeline connections to prevent water leakage and ensure the normal operation of the pipeline system. It can bond pipes of different materials to ensure sealing effect.
