Modified Polyolefin (Waterborne & Solventborne)

Product Description

This series of products is modified polyolefin, chlorine-free adhesion promoter. We have developed and produced two types of this product, namely HG-CohesivePro 2009-A and HG-CohesivePro 2009-B. HG-CohesivePro 2009-A is waterborne high molecular weight anhydrous modified polyolefin, while HG-CohesivePro 2009-B is a solvent-based modified polyolefin. The application, properties and features of two products are described in detail below, and please see to find the suitable product for your projects.

HG-CohesivePro 2009-A

HG-CohesivePro 2009-B

HG-CohesivePro 2009-A

Applications

• HG-CohesivePro 2009-A can be used as an effective adhesion promoter between different types of plastics and between plastics and polar substrates.
• HG-CohesivePro 2009-A can be used as effective adhesion promoter for printing inks for laminated films.
• HG-CohesivePro 2009-A can be used as excellent additive to adhesive used between wood and low surface energy substrate.

*Comments: The properties given here are typical of average lots. Alfa Chemistry does not represent that products in any particular batch will exactly conform to the values given.

Application Methods

• If used as a primer: Approximately 1.0 to 5.0% of HG-CohesivePro 2009-A is dissolved in deionized water and then adding 0.5% surfactant and 30% by wt. alcohol into the above dilution to improve the wettability and drying time. Apply the dilution to a clean surface (surface free of dirt, oil, grease, and others) with a spray, brush, roll, or stick, and make sure the surface completely covered. The topcoat can be applied as soon as the primer is dry (usually 5 to 30 minutes at 50°C to 100°C or at least 24 hours at room temperature).
• If used as an additive: Depending on the purpose of use, approximately 0.5 to 1% of HG-CohesivePro 2009-A is added to printing ink system and approximately 0.5 to 5% of HG-CohesivePro 2009-A is added to adhesives system. (please ensure that the product is compatible in the system).

*Comments: The properties given here are typical of average lots. Alfa Chemistry does not represent that products in any particular batch will exactly conform to the values given.

Application Methods

Typical procedures for coating primer are described as follow:

• First, clean the substrate with IPA solution to obtain surface free of dirt, oil, grease, and others.
• After the substrate surface is completely dry, apply the product to a clean surface with a Meyer rod, blade coater, spray or brush. (Loading levels can range from 1-10% depending on the purpose of use.)
• Finally, apply the topcoat after the primer is fully cured at ambient or elevated temperature.
