PRODUCT INFORMATION DATA SHEETS TIECOAT PRIMER PRODUCT DESCRIPTION Tie-Coat Primer is a very tough and sandable, non-moisture sensitive single-component polyurethane primer. It contains hybrid polymeric resins which have excellent adhesion characteristics to most painted surfaces, especially that of POR 15, because we have matched and blended the resin components of both coatings to make them fully compatible. Tie-Coat Primer is highly resistant to penetrating topcoats such as enamels, lacquers, and two-component finishes (“penetrating topcoats” refers to topcoats with especially aggressive solvent bases which can penetrate and ruin a partially cured base coat). Tie-Coat Primer is not a reactive coating (as is POR 15, which reacts to moisture), but its revolutionary adhesion promoters make it an ideal interlocking prime coat between POR 15 and various topcoats. It sands to a perfectly smooth finish. It may be use over well seasoned POR 15 coatings even if they are more than a year old with no special preparation other than cleaning the surface.

Ceiling Value OSHA PEL: 500 DIRECTIONS FOR USE Surface Preparation: Surface to be coated should be free of grease, oil, foreign substances. Use a wax and grease remover before painting. Marine Clean is ideal for this. Avoid the use of Solvent based preps. Thinning: Thinning is not usually required. May be thinned up to 10% with POR 15 Solvent. Do not thin anymore than this or adhesion maybe affected. Application: Stir Tie-Coat thoroughly before using; do not shake as this will create air bubbles. Apply by brush or spraying. Apply in thin coats, if applied too heavily drying time will be lengthened considerably. Subsequent coats may be applied at 12 hour intervals if desired. DO NOT SAND BETWEEN COATS OF PRIMER. Sand only after final coat of primer has fully dried (24 hours). Pressure: Spray at approximately 250 Kpa (35lbs). Topcoating: Allow a minimum of 24 hours before applying any topcoat over Tie-Coat Primer. Failure to allow enough dry time before applying topcoats may result in spidering or crinkling of the finish. NOTE: in temperatures below 18 C curing times can lengthen considerably (Tie-Coat is Solvent curing not moisture curing) allow extra days for curing in a low temperature environment. Tie-Coat will stop curing in temperatures below 12 C. Storage & Handling: Store in a tightly closed container and protect from moisture and foreign materials. Idea storage temperature storage is 10 - 27 C (50-81 F). SUMMARY: - Stir, do not shake, Tie Coat Primer before using.
- Apply thin coats. Do not sand between coats. Sand only after final coat has dried thoroughly - watch drying times — see note.
- As with all solvent-based coatings, use an organic vapour particulate respirator, NIOSH/MSHA approved, when spraying or brushing. In closed areas, use an air supplied respirator when spraying.
