Parasilico EPDM - Neutral oxime type silicone - DL Chemicals

Parasilico EPDM - Neutral oxime type silicone - DL Chemicals

Neutral oxime type silicone , specially designed for sealing EPDM roofing .

Given the wide variety of EPDM membranes, prior compatibility tests are necessary .

• Neutral 1-component silicone
• Permanent elasticity
• Very easy to apply
• Good resistance to low and high temperatures
• Excellent adhesion to almost all building materials
• Good adhesion to EPDM
• Compatible with most perimeter seals for insulating glass units as well as with PVB safety glass films
• Very good UV resistance
• Very good resistance to aging and weathering

Applications:

• EPDM waterproofing (given the wide variety of EPDM membranes, prior compatibility tests are necessary).

Instructions for use:

1. Preparation :
   • Do not apply in confined spaces. It is important to ventilate the areas well during application and curing.
   • The surfaces must be solid, dry and free from dust and grease.
   • If necessary, degrease with Parasilico Cleaner , MEK, alcohol or ethanol.
   • The user must ensure that the product used is suitable for their intended purpose. If necessary, contact our technical support.
2. Primary schools:
   • Absorbent surfaces: Silicone Primer Porous Surfaces (transparent, drying time approx. 60 min.).
   • Non-absorbent surfaces: Silicone Primer Non-Porous Surfaces (transparent, drying time approx. 60 min.).
   • The use of a primer may be necessary on very porous surfaces, in cases of poor adhesion or under demanding conditions of use.
3. Laid :
   • Apply the product from the cartridge/pouch with a manual or pneumatic caulking gun.
   • The size and shape of the joint are very important. Avoid thin joints.
   • Do not apply thermal, mechanical or chemical loads before complete hardening.
4. Joint dimensions:
   
   • Allowable joint widths from 5 mm to 30 mm
   • For joints up to 10 mm wide: the joint depth must be equal to the joint width. For joints wider than 10 mm: the joint depth = (joint width/3) + 6 mm
5. Smoothing:
   • Smooth before skin formation with Perfect Joint Tooling Smoothing Agent Liquid and/or with the Perfect Joint Tool Smoothing Palette
   • Avoid getting any tooling agent on the surface before applying silicone. Silicone will not adhere to a wet surface.
6. Cleaning:
   • To clean tools and surfaces and remove residue before hardening, use Parasilico Cleaner , Multi-purpose Super Cleaner , or Cleaning Wipes . Hardened residue can be removed with Silicone Remover.
   • After hardening, mechanically remove the hardened elements.
7. Repair :
   • With the same product.

Packaging:

300 ml cartridge: Graphite black

600 ml pouch: Graphite black

FAQ - Frequently Asked Questions

1. Can Parasilico EPDM glue elements directly onto an EPDM membrane?
   Yes, it is designed for that. It ensures excellent adhesion without primer on quality EPDM membranes.
2. Can this silicone be used underwater or for permanent immersion?
   No, it is resistant to standing water but should not be used for continuous immersion.
3. Does the sealant contain acid?
   No, it is a neutral oxime silicone, therefore compatible with sensitive materials (metals, natural stone, plastics…).
4. Is the product suitable for outdoor use?
   Yes, it offers exceptional resistance to UV, ozone and weathering, ideal for exterior roofing.
5. Can Parasilico EPDM be painted?
   Like all silicones, it cannot be combed.
6. Can it be used on concrete or porous surfaces?
   Yes, but on very porous or friable surfaces, applying a primer can improve adhesion.
7. What is the shelf life of the product?
   Generally 12 months in its original closed packaging, stored between +5°C and +25°C.
8. Is it compatible with bitumen?
   Yes, on dry and old bitumen. Do not apply on fresh or exuding bitumen.
