Silicone Sealants

Howell Silicone Sealants provide strong adhesion, tensile strength, and excellent weather resistance, making them ideal as high heat silicone sealant. Their quake resistance, electrical insulation, moisture-proof, leak-proof, and odor resistance properties also make them suitable for automotive silicone sealant applications. Furthermore, their durability and resistance to mildew and moisture make them an excellent choice for bathroom silicone sealant. Howell Silicone Sealants deliver versatile performance for a wide range of applications, including in high temperature, automotive, and bathroom environments.

Anaerobic sealants

Howell specializes in the research and development, as well as the manufacturing, of anaerobic sealants specifically designed for flange sealing and pipe thread and joint locking. These sealants, ideal for metal-to-metal interfaces, cure in the absence of air, ensuring leak-proof, vibration-resistant seals. Essential in industries like automotive, aerospace, and heavy machinery, Howell's products offer robust strength and durability. Their expertise in anaerobic technology has made them a leader in the field, providing reliable and efficient sealing solutions that adhere to stringent industrial standards.

Chemical Corrosion Resistance Fiberglass Tissue

Fiberglass Tissue

The fiberglass tissue is made of chopped fibers, which are randomly and evenly distributed into continuous fiberglass paper sheets by paper-making method, and bonded with binder. Its main performance & characteristics : chemical corrosion resistance, fire resistance, flame retardant, waterproof, aging resistance, weather resistance, insulation and other characteristics. The fiberglass tissue is widely used as reinforced plastic substrate, anti-corrosion, thermal insulation, fire retardant, waterproof materials, gypsum board ceiling building materials, VOCSCR carrier, PVC floor and carpet substrate, epoxy copper clad laminate and electrical insulation products.

Roof Coating

Whether your roof is large or small, flat or sloped, Silicone Roof Coatings provide a proven, guaranteed solution for renewing your weathered roof. They can be applied to virtually any existing roofing surface to create a seamless membrane that protects against permanent ponding water, ultraviolet light and severe weather. 
 
The key advantages of using a silicone roofing coating are: 
  • Silicone is permanent and will not degrade, chalk or crack under harsh UV rays. 
  • Silicone forms a seamless membrane that withstands permanent ponding water without softening. 
  • Silicone creates a smooth surface that offers excellent resistance to mold, mildew and staining.
 
AVOID TIME-CONSUMING AND COSTLY TEAR-OFFS. 
By re-covering, you save on labor costs and avoid landfill expenses, plus your existing roof can be re-covered without any interruption to normal business operations. 
 
EXTEND THE LIFE OF YOUR ROOF. By renewing your roof, you’ll never need to replace the roof again. REDUCE ENERGY COSTS. The highly-reflective, glossy finish of Silicone Roof Coatings can help reduce energy costs. 
 
IDEAL FOR USE ON FLAT AND LOW-SLOPED ROOFS. 
Apply over pre-existing elastomeric roof coatings, metal roofs, built-up roofing, mineral cap sheet, and weathered single ply membranes (EPDM, Hypalon® and TPO/CPA). Re-coat existing sprayed-in-place polyurethane foam, concrete, wood, and many other coatings
