| Brand Name | Dongyuan |
The Dongyuan single-component polyurethane foam sealant for winter is a product suitable for operation in low-temperature environments. It can foam normally in low temperatures and also has excellent insulation, soundproofing, bonding and sealing effects at low temperatures. This product is available in both gun-type and tube-type specifications.
Product features
It can be used normally even at -10℃;
Pre-expanded, with good stability, no shrinkage or post-expansion;
The foam is fine and has strong adhesion;
Excellent heat insulation, sound insulation, bonding and sealing effects
Application scope
Normal foaming occurs at room temperature, with excellent performance;
Suitable for various low-temperature operations, with excellent foaming effect;
Suitable for installation of doors and windows, and for filling gaps in buildings.
Surface treatment
Ensure that the bonding surfaces are clean, free of dust and grease; remove loose particles;
Appropriate water spraying on the bonding surfaces can enhance the bonding effect and accelerate the curing speed of the foam.
Instruction Manual
Before use, shake the canister at least 20 times; wet the bonding surface with water; for deeper holes, spray water on the interface for each layer of foam to ensure that the foam is fully cured and there is good adhesion between each layer. Unsolidified foam can be cleaned with a cleaning agent, while solidified foam should be removed by mechanical methods.
Storage
The product should be stored upright in a dry environment with a temperature ranging from 5 to 35 degrees Celsius; during storage, avoid direct sunlight or exposure to temperatures exceeding 50 degrees Celsius. The product has a shelf life of 9 months. Note: High temperatures will significantly reduce the shelf life of the product.
