Introduction:
Escoat RA-130W Release Coat is a non-silicone, acrylic water based emulsion which provides superior release characteristics when applied to polyethylene and polyester films. Escoat RA-130W has a strong wetting and adhesion performance with PET and corona treated PE substrates. Escoat RA-130W is useful for duct tape and other tapes where an aqueous coating is needed.

Mixing Instructions:
Depending on the type of substrate and pressure sensitive adhesive, the concentration of solid matter required should be determined by laboratory trial. Escoat RA-130W Release Coat diluted to between 2.0% to 5.0% solids will be adequate in most pressure sensitive applications. Stir well before use.
Applications:
Escoat RA-130W Release Coat is diluted in water to achieve application concentrations. Depending on the substrate and adhesive, the solids concentration should be determined by lab test. Recommended levels are between 2.0 – 5.0%. Film substrates should be corona treated to ensure adhesion to the substrate. Coat at 4 – 5 gm/m2 (wet coat weight) using conventional coating methods with Meyer rod, Anilox or Gravure rollers. Coated substrate must be thoroughly dry before rewinding.
Advantages:
- Offers an easy peel release. The smooth release properties are similar to PVODC release coatings.
- Cost Efficient. Excellent release can be obtained using as little as 2.0% solids concentration, depending on film, adhesive, coating equipment and desired release levels. The 51-52% solids allow less water to be shipped.
- Low temperature curing.
- A glossy coating.
- Can be used with aggressive solvent, hot melt or aqueous acrylic adhesives.
