Product Description

HG-CohesivePro 2008 is ethylene copolymer dispersion, which is a water-based chlorine-free adhesion promoter. It is designed for polyethylene substrates and to work on surfaces without any surface treatment such as corona or flame. HG-CohesivePro 2008 can be used as a primer or as an additive to a coating formulation.

Features

Some notable features of HG-CohesivePro 2008 include:

  • Superior adhesion to LDPE and HDPE
  • Cured at elevated temperature
  • Excellent interlayer adhesion between primer and top coat (polyester, alkyd or polyurethane paint).

Application Methods

Typical procedure for coating primer on polyolefin are described as follow:

  • First, clean the substrate with suitable solvent to obtain surface free of dirt, oil, grease, and others.
  • Then, dilute the product with water to a solution with a solid content of 3% to 10% to prepare the primer solution. And then add wetting agent to improve the wettability.
  • Next, using a Meyer rod, blade coater, spraying or brushing to apply the primer solution to the substrate.
  • Finally, apply the topcoat as soon as the primer is dry (usually 5 to 15 minutes at temperatures above 82°C.).
