Polyether polyol for coating is an important organic polymer, mainly used in the preparation of coatings and adhesives. It is prepared by polyaddition reaction of initiator (compound containing active hydrogen group) with ethylene oxide (EO), propylene oxide (PO), butylene oxide (BO), etc. in the presence of catalyst. The main chain of polyether polyol contains ether bond (-R-O-R-), and the end group or side group contains more than 2 hydroxyl groups (-OH).
The polyether polyol for coating, it's the CASE polyether ,can be also call Polyether-based polyurethane coatings,it has excellent properties, including enhanced hydrolytic stability, good flexibility, good hardness and strength, good durability, and good chemical resistance, which make them ideal for coating applications.
Application
Polyether polyols for coatings have a variety of uses in coatings and adhesives:
Coatings: Polyether polyols can be used as high-performance epoxy resin prepolymers to prepare high-performance epoxy resin coatings to improve the coating's wear resistance, adhesion, solvent resistance and strength.
Adhesives: In adhesives, polyether polyols can undergo a variety of chemical reactions with other compounds to enhance the adhesive's adhesion and performance.
Our polyether polyol for coating series, based on propylene glycol. The product has no BHT, widely used to the preparation of polyurethane elastomer, adhesive, waterproof coating, sports paving materials, etc.
Apply to the basement (basement of the building, basement parking lot, open-cut subway and passageway);
Apply to bathrooms, swimming pools, balconies, and parking areas;
Apply to non-exposed roof waterproof engineering;
Apply to waterproof engineering of swimming pools, artificial fountains, water pools, and water cana;
Apply to waterproof engineering of the roof for parking lots and squares;
Properties
Physical and chemical properties of polyether polyols for coatings:
High molecular weight: usually has a higher molecular weight, providing good physical and chemical properties.
- Low viscosity: easy to process and apply.
- High activity: due to the presence of multiple hydroxyl groups, it has high reactivity.
- Hydrophilicity: ether bonds make it hydrophilic to a certain extent, which helps solubility and dispersion.
- Improved hydrolytic stability: When compared to polyester-based coatings, polyether-based polyurethane coatings have improved hydrolytic stability and superior resistance to weak acids and bases.
- Excellent adaptability: the blended polyol for polyether polyols provide significantly more product flexibility, which is useful for coatings that require flexibility.
- Good hardness and strength: Polyester polyols give the product good hardness and strength.
- Long service life: Polyether polyols have a long service life and can preserve the qualities of coatings.
- Good chemical resistance: Polyether polyols have good chemical resistance, which allows them to withstand the corrosion of acids, alkalis, and solvents while also maintaining coating stability.
