SiMP Fix Crystal | Transparent One-Component SiMP Elastic Adhesive & Sealant

SiMP Crystal is a transparent, one-component elastic adhesive and sealant in a caulking gun form, non-sagging, utilizing silyl-modified polymer (SiMP). The adhesive cures under the influence of atmospheric moisture, forming a high-performance compound with permanent elasticity and excellent weather and aging resistance. The product is solvent-free and isocyanate-free.

• Crystal-clear transparency

• Excellent aging and weather resistance; color stability, no yellowing, and no chalking

• Environmentally friendly – No isocyanates or solvents

• No hazard warning symbols required

• No bubble formation – Odorless

• Bonds and seals simultaneously

• Permanent flexibility

• Easy application with superior consistency

• Excellent thixotropy, non-sagging, short bead break

• No volume change, no shrinkage

• Excellent adhesion without primer on all common construction and industrial materials

• Does not stain concrete or porous materials

Application

SiMP Crystal is a versatile, high-performance, transparent adhesive and sealant, ideal for various applications in interior installation, construction finishing, furniture, and industrial assembly where a clear bond or seal is required. It is suitable for transparent handrails and balconies, waterproofing joints on transparent roofing, and bonding window or door frames, as well as for mirror and glass assembly. It is perfect for DIY projects and retail craft items, with fully transparent packaging.

Technical Data

Instructions for Use

Surfaces to be bonded must be thoroughly cleaned, dry, and free from dust or grease. Pre-treat the bonding surface according to NPT’s application guidelines, and use specific CLEANER or ACTIVATOR from NPT’s product line. Preliminary adhesion testing on the supporting surface is recommended.

Attach the nozzle and cut it to the desired angle to create the desired thickness and shape of the adhesive bead. Insert the adhesive cartridge or tube into a manual or pneumatic caulking gun (equipped with a telescopic piston) and carefully extrude the adhesive, avoiding air entrapment. After opening the package, use the adhesive within a short period. The optimal working temperature for both the surface and adhesive is between 15°C and 25°C.

Shaping and finishing must be done while the adhesive is still tacky. SiMP Crystal can be painted over; however, paint compatibility should be tested through preliminary trials. Caution is advised when using alcohol-based or alkyd resins, as they may interfere with the curing process of the adhesive and extend the drying time of the paint. The hardness and thickness of the paint layer can affect the elasticity of the adhesive and lead to paint cracking.

Do not allow curing in the presence of curing silicone sealants. Avoid contact with solvent-based cleaning agents during curing. When applying the adhesive, avoid air entrapment. Since this system cures with moisture, ensure sufficient exposure to air. Bonded parts may require additional holding or support during the curing stage.

Cleaning Instructions

Clean used tools with acetone or solvent. When the adhesive is uncured, it can be wiped off with paper or cloth. Once the adhesive has cured, it can only be removed mechanically. Avoid direct skin contact by wearing latex, rubber, or polyethylene gloves. If the adhesive contacts skin, remove immediately and wash with soap and water.

Storage Instructions

SiMP Crystal can be stored for 12 months in its original (unopened) packaging at temperatures between 10°C and 25°C in a dry, cool place. The storage temperature should not exceed 25°C for extended periods. Keep away from damp areas, direct sunlight, and heat sources.
