Application of CONATHANE® EN-16
Polyether-based system primarily intended for use as a molding, encapsulating and potting compound for harness breakouts, watertight electrical connectors, cables and cable end seals.
Other applications include casting and molding of mechanical parts and lining material for pumps, chutes and conveyors requiring outstanding abrasion resistance.
Application/Curing Schedule
Mix the EN-16 Part A and EN-16 Part B in the ratio specified above until homogeneous. Components may be preheated up to 60°C if reduced viscosity is required. If hand mixing, degas at >27 in. Hg vacuum before use.
EN-16 potting compound and encapsulant may be applied by ordinary casting techniques or by injection molding techniques. For most injection molding applications, injection pressures of 40 – 120 psi are generally used. If molding compound is injected at elevated temperatures (60°C / 140°F to 82°C/ 180°F), lower injection pressures (10 – 30 psi) should be used to prevent air from being entrapped in the compound.
Best results are obtained when the part being molded and the mold itself are approximately 10 – 20°F (5 – 10°C) warmer than the compound being injected. It is recommended that injection holes be located in the bottom of the mold and air bleed holes located in the top of prevent air pockets in the mold.
Cure 7 days at 25°C / 77°F – or – 16 hours at 80°C / 176°F.
The cure schedules above are based on time after the unit reaches the specified temperature and are recommendations only. The user is responsible for determining the optimum cure conditions for his application.
To approve adhesion, three primers have been developed for use with the EN-16. CONAP® AD-1146 is recommended for metals, CONAP® PR-1167 for neoprene and CONAP® AD-1161 for polyvinyl chloride.
Molds may be coated with CONAP® MR-5002 mold release to ensure easy removal of cast parts.
Transportation/Storage
Store below 25°C / 77°F in a dry controlled environment out of direct sunlight. This material should be suitable for use stored under these conditions in the original sealed containers for twelve (12) months from the date of shipment.
Failure to store the product as recommended above may lead to deterioration in product performance. This product is sensitive to moisture and atmospheric humidity. Containers, once opened, should be used immediately or blanketed with dry air or nitrogen (CONAP® Dri-Purge) before resealing.
Mix individual components thoroughly before use.
CONATHANE® EN-16 Part A and EN-16 Part B may crystallize upon storage or during shipment. If this has occurred, heat to 60°C, mix thoroughly and cool to room temperature before processing.
