Wholesale Fast Curing Rosin-modified UV Resin for Inks

Product Description of UV Resin

Product name: UV Resin

Other names: UV-curable ink resin, modified rosin UV resin

Type: AR-941

Classification: UV Oligomers/Polyester Acrylate/UV Resin

Through chemical modification, it retains the excellent properties of rosin resin while significantly improving cure speed, resistance, and pigment compatibility. It also offers exceptional cost-effectiveness, making it an ideal raw material for UV curing applications.

Key Features

1. Fast Curing: High reactivity of UV resin shortens the curing time of UV printing inks and UV varnish, thereby improving production efficiency.
2. Excellent Pigment Wetting: Effectively wets and disperses a variety of pigments, preventing flocculation and sedimentation, enabling the production of high-gloss, rich, and stable inks and coatings.
3. Excellent Water Resistance: The cured film effectively resists moisture intrusion. It does not readily blush or soften, making it suitable for packaging products exposed to humid environments.
4. Excellent Solvent Resistance: Excellent resistance of UV resin to common solvents such as alcohols and esters. This can ensure the stability of printed products or coatings during post-processing (such as lamination and varnishing) or during use.
5. Competitive Price: Competitive price, helping customers effectively control costs while ensuring product quality. High cost-performance is one of the key factors that helps iSuoChem's customers quickly capture the local market. It is also a key reason why many customers choose us. Our products are a perfect match for popular international brands.

Application

1. UV offset printing ink
2. UV screen printing ink
3. UV varnish
4. UV coating

UV Resin Specifications

Packaging and Storage

Net weight: 20KG per bag or 100KG per bag.

The UV resin should be stored in a cool, dry place away from direct sunlight. Avoid UV resin exposure to sunlight and heat sources. The storage temperature should not exceed 40°C. Under normal conditions, the storage stability is at least 6 months.

FAQ

Q: What are UV oligomers?

A：UV Oligomers (also called UV prepolymers), the core components of UV varnishes, come in three main types: epoxy acrylates (fast-drying, chemically resistant, but brittle); polyester acrylates (flexible, with good adhesion but poor durability); and polyurethane acrylates (abrasion-resistant, highly elastic, but expensive and slow to cure). Each has its own advantages and disadvantages, and selection should be based on the material (such as rigidity or flexibility) and performance requirements (such as hardness or toughness).

UV oligomers are relatively high molecular weight materials. It offers vital properties to UV printing inks, UV Varnish, UV coatings, and adhesives. It is designed to enhance the curing speed, durability and quality of various printed materials

Q: What is the relationship between UV Resins and UV Oligomers?

A:These UV oligomers serve as the "backbone" of the UV resin system. Together with other ingredients such as reactive diluents and photoinitiators, they form the complete UV resin product and directly determine the key properties of the cured coating (such as hardness, flexibility, and durability). The choice of oligomer is therefore central to UV resin formulation design.
