ASI 504 Commercial Grade Silicone Sealant Adhesive is a one-part, moisture- curing RTV (room temperature vulcanizing) silicone that cures to a strong, silicone rubber that maintains long-term durability and  flexibility. ASI 504 contains no solvents or isocyanates which makes it VOC compliant. Due to the formulation, ASI 504 works well for a variety of applications. ASI 504 is a non-slump sealant and can be applied to vertical or overhead surfaces without flowing or sagging. ASI 504 also has excellent resistance to weathering including ozone, ultra-violet radiation, freeze-thaw conditions and airborne chemicals. ASI 504 can be applied to surface temperatures from -18°C to +50°C (0°F to +120°F) and after curing, withstands constant operating temperatures from -57°C to +205°C (-70°F to 400°F).

Directions:

ASI 504 is ready to use and requires no mixing or additives. The cure mechanism begins as soon as the sealant comes in contact with the air. At conditions of 25°C (77°F) and 50% relative humidity, the sealant will skin in 10 minutes and fully cure
in 24 hours (1/8” bead) and reaches its maximum adhesion in 7 days. Higher humidity accelerates curing. Tooling, if necessary, should be done before skinning takes place. In applications where partial or total confinement of sealant is prevalent, the time
required for proper cure is generally lengthened by the degree of confinement.


Surface Preperation:
All surfaces should be clean and dry. If necessary bonding surfaces can be solvent wiped with naphthas, ketones or chlorinated solvents. Specific solvents would include xylol, toluol and mineral spirits. In case of plastics, determine suitability of solvent prior to use. Allow surface to dry thoroughly before applying sealant. Do not solvent wipe with alcohols or oil-containing solvents such as Varsol. Priming for ASI 504 is not normally required for applications to nonporous surfaces. Unprimed adhesion can be easily tested by applying a small trial bead and allowing 7 days for maximum adhesion to occur. If primer is required, contact ASI.

 

Safety Precautions:
ASI 504 releases small amounts of acetic acid during cure. Adequate ventilation should be provided with extensive use of this sealant. On direct contact, uncured sealant may irritate eyes. Flush eyes well with water and call a physician. Avoid prolonged contact with skin.


Storage:
ASI 504, when stored in original, unopened container at or below 32°C (90°F), has a shelf life of 12 months from date of shipment.


Warranty Limitations:
ASI warrants only that its products will meet its specifications. ASI shall in no event be liable for incidental or consequential
damages. Except as expressly stipulated, ASI’s liability, expressed or implied is limited to the stated selling price of any defective goods.
