الخصائص والمزايا:

Latent waterborne curing agent RG-2822，This curing agent can coexist stably with resin containing active groups (hydroxyl groups, carboxyl groups, amino groups, epoxy groups, etc.) at room temperature. After being heated at 110-120℃, the -NCO groups released by this product can react with hydroxyl groups, carboxyl groups, amino groups, etc. to form cross-links, significantly improving the color stability, adhesion, bonding strength and sterilization resistance of polyurethane, polyester, alkyd resin and acrylic resin, etc. It also has excellent resistance to yellowing.

مواصفات المنتج:

Application fields:

1. As an internal crosslinking agent for single-component thermosetting water-based coatings, it significantly improves the water resistance, chemical resistance, wear resistance, adhesion, mechanical properties, etc. of water-based resin coatings through curing and crosslinking.
2. As an auxiliary agent for “three protection” emulsions, it fixes organic fluorine/organic silicon onto the surface of cotton fibers or polyester fibers, increasing the number of water washes of “three protection” fabrics.
3. As an internal crosslinking agent for textile coatings and printing pastes, it enhances adhesion and properties such as water wash resistance, durability, and color stability.
4. As an internal crosslinking agent for single-component metal baking paints, it can replace amino resins, improving brittleness, without formaldehyde release, and having excellent yellowing resistance performance.
5. Treatment agent for polyester or polyester cord fabric, improving the bonding performance between polyester and rubber.

طريقة الاستخدام:

According to different uses, add in a certain proportion. The recommended dosage is 3%-8%. Adjust as per experimental results.

التخزين:

In a cool, ventilated, and dry warehouse, it can be stored for more than 6 months.
