Data Sheet for Wearlon 2020.90        - Primer - Protective Coating -

APPLICATION GUIDE AND TECHNICAL INFORMATION
Meets EPA, USDA, And FDA 21 CFR 175.300 Requirements

Surface Preparation

Wearlon® 2020.90 is a silicone-epoxy having unique adhesion properties to a broad range of substrates. The adhesion properties, excellent elongation and water resistance properties make it ideal for a protective coat or a primer coat. Proper substrate treatment is sometimes necessary. (Steel: SSPC 10. Aluminum: SSPC 7. Fiberglass: 80 grit sand. Concrete: 28 day minimum cure and power wash using acid etch or shot blast.)

Mixing Instructions

Before mixing, shake or stir each component until homogenous.

Wearlon® 2020.90 is a 2 component product packaged in 1 Gallon and 5 Gallon kit which contain the proper ratio of ingredients. The entire contents of each container should be mixed together.

For quantities less than the pre-packaged kit, mix as follows: To 11 parts of the A component mix in 2 parts of the B component. Mix the A and the B until completely blended.

NO INDUCTION PERIOD NECESSARY... Spray or Roll immediately.

Thinning and Clean up

In most cases it is not necessary to thin Wearlon® 2020.90. If you find it necessary to thin Wearlon® 2020.90 you may add up to 5% DRINKING WATER. Clean up by using soap and water while Wearlon® 2020.90 is in an uncured state. For best results clean all equipment as soon as the application is complete. After the material has cured you will need to use solvents to remove the Wearlon® 2020.90

Application and Recoating

Product can be rolled, brushed or sprayed. For best results, spray Wearlon® 2020.90 with airless spray equipment. Conventional spray equipment works well and provides a slight orange peel finish. For a greater orange peel effect apply Wearlon® 2020.90 with a short nap Mohair roller or Urethane foam roller. Roll 1 coat, and then follow within 30-45 min. with the 2nd coat to achieve your total mil thickness.

FLASH RUSTING can be readily eliminated by applying a mist coat of Wearlon® 2020.90 using spray or a foam roller for less than a 1 mil wet deposit. Curing this light deposit of 2020.90 prior to any subsequent Wearlon coating will eliminate flash rusting. Applying Wearlon to a warm surface, 100°F to 140°F will eliminate flash rusting while speeding up the cure of the coating.

Shelf Life: 1 Year Storage: DO NOT FREEZE
