PU328-18K High-Viscosity Water-Based Resin for Bright Dyeing of Fire Hoses

Product Description

This product is a high-viscosity water-based resin produced by hybridizing acrylic monomers and aliphatic polyurethane. The film is soft and glossy. It is specifically used for bright coating and dyeing of fire hoses.

Dyeing Principle

Fire hose membrane coating dyeing involves creating a coating adhesive by mixing water-based resin, water-based color paste, and color fixative in a certain proportion. The coating is applied evenly to the surface of the hose using a coating process, then dried at a high temperature. The water-based resin forms a colored resin film on the surface, creating a bright, water-resistant, and wear-resistant colored fire hose.

Physicochemical Indicators

Product Characteristics

▪ Primarily used for bright dyeing of the surface membrane of polyester and polyester-cotton fire hoses

▪ Good color fastness, wear-resistant, and water-resistant

▪ Strong covering power, no color difference, not easy to produce dyeing defects

▪ The dyed surface has good anti-aging properties, does not become sticky at high temperatures, and does not mildew

▪ Free of APEO, formaldehyde, heavy metals, and other harmful substances; it is an environmentally friendly emulsion

Fire Hose Coating Reference Formula

Process Flow

Mechanical coating (room temperature) → Infrared drying (infrared or hot air) → Drying (80～120℃, 5～8min) → Post-treatment → Inspection → Packaging.

Precautions

▪ The dyeing coating adhesive should not be prepared for more than 24 hours to prevent premature reaction of the water-based resin, which may cause serious thickening or skinning, thus hindering normal dyeing.

▪ Drying should be done using non-contact methods, such as infrared or hot air drying; drum drying is not recommended.

▪ Thorough drying is necessary; otherwise, color fastness and membrane gloss will be affected.

Packaging and Transportation

▪ This product is packaged in plastic barrels, with a net weight of 50Kg or 125Kg.

▪ This product is a water-based emulsion, non-flammable, and non-explosive; it is transported as non-hazardous goods.

▪ This product should be stored and transported at 5-35℃, with a shelf life of 6 months.
