Read more| Exterior sealant and direct glazing adhesive for organic glass in Marine applications Sikaflex-295 UV is a 1-component polyurethane adhesive of paste-like consistency that cures on exposure to atmospheric moisture. It is suitable for interior and exterior sealing applications and to bond organic glass in the Marine business. Sikaflex-295 UV meets the requirements set out by the International Maritime Organization (IMO).

PRODUCT BENEFITS
UsageSikaflex-295 UV has been specially developed for the marine industry, where it is used to bond and seal plastic glazing materials in boats and ships. Because of its excellent weatherability this product can also be used to seal joints in exposed areas. Suitable substrates are aluminium (bright or anodized), GRP (polyester resin), stainless steel, timber, 2-component coatings and plastic glazing materials (PC, PMMA). Seek manufacturer’s advice and perform tests on original substrates before using Sikaflex-295 UV on materials prone to stress cracking. This product is suitable for experienced professional users only. Tests with actual substrates and conditions have to be performed to ensure adhesion and material compatibility.Packaging

Technical Information CURE MECHANISM Sikaflex-295 UV cures by reaction with atmospheric moisture. At low temperatures the water content of the air is generally lower and the curing reaction proceeds somewhat slower (see diagram 1). Diagram 1: Curing speed Sikaflex-295 UV CHEMICAL RESISTANCE Sikaflex-295 UV is generally resistant to fresh water, seawater, diluted acids and diluted caustic solutions; temporarily resistant to fuels, mineral oils, vegetable and animal fats and oils; not resistant to organic acids, glycolic alcohol, concentrated mineral acids and caustic solutions or solvents. | ||||||||||||||||||||||||||||||||||||||||||||||||||
Application Information Surface Preparation Surfaces must be clean, dry and free from grease, oil, dust and contaminants. Surface treatment depends on the specific nature of the substrates and is crucial for a long lasting bond. Suggestions for surface preparation may be found on the current edition of the appropriate Sika Pre-treatment Chart. Consider that these suggestions are based on experience and have in any case to be verified by tests on original substrates. Application Sikaflex-295 UV can be processed between 10 °C and 35 °C (climate and product) but changes in reactivity and application properties have to be considered. The optimum temperature for substrate and adhesive sealant is between 15 °C and 25 °C.

Sikaflex-295 UV can be processed with manual, pneumatic or electric driven piston guns as well as pump equipment. The open time is significantly shorter in hot and humid climate. The parts must always be installed within the open time. Never join bonding parts if the adhesive has built a skin. Tooling and finishing Tooling and finishing must be carried out within the skin time of the product. It is recommended using Sika Tooling Agent N. Other finishing agents must be tested for suitability and compatibility prior the use. Removal Uncured Sikaflex-295 UV can be removed from tools and equipment with Sika Remover-208 or another suitable solvent. Once cured, the material can only be removed mechanically. Hands and exposed skin have to be washed immediately using Sika Cleaner-350H cleaning towels or a suitable industrial hand cleaner and water. Do not use solvents on skin. Overpainting Sikaflex-295 UV can be painted prior and after formation of a skin. If painting process takes place after the sealant has built a skin, the adhesion could be improved by treating the joint surface with Sika Aktivator-100 or Sika Aktivator-205 prior to paint process. If the paint requires a baking process (> 80 °C), best performance is achieved by allowing the sealant to fully cure first. All paints have to be tested by carrying preliminary trials under manufacturing conditions. |
