SACM450-C CHEMICAL & ANTI-CORROSION TISSUE (450g/m²)
Lightweight veils fail to hold enough corrosion-resistant resin on large GRP tank walls.
SACM450-C provides a heavy 450g/m² structural barrier that seals inner liner surfaces, blocks acid attack, and stops costly tank rejections.
SACM450-C CHEMICAL & ANTI-CORROSION TISSUE (450g/m²)
Holds 90% Resin. Blocks Acid Leaks.
SAXOBRAN® Our team designed SACM450-C because we saw chemical tank builders lose money when thin liners cracked under chemical load. We found that lightweight veils fail to hold enough corrosion-resistant resin on large GRP tank walls. SACM450-C provides a heavy 450g/m² structural barrier that seals inner liner surfaces, blocks acid attack, and stops costly tank rejections.
Industrial Pain Points Solved.
Severe Corrosion Seepage and Liner Failure
Strong chemical fluids penetrate thin surface veils and attack the structural glass layer underneath. This causes liner cracking, toxic tank leaks, and total failure during hydro-testing.
We pack 450g/m² of high-purity C-glass strands into a heavy protective mat. It maintains a 90% resin-rich barrier that stops acid and alkaline fluids from reaching the structural wall.
Resin Run-Off and Dry Void Traps
Heavy glass mats often wet out poorly, trapping micro-voids inside vertical tank walls. Under chemical pressure, these dry spots blister and cause inner liner delamination.
Uses a fast-dissolving powder binder that wets out completely in under 15 seconds. Resin locks onto the fiber network instantly, leaving zero dry air voids on vertical surfaces.
Engineered Characteristics
Ultra-Thick Chemical Shield
Forms a heavy, resin-rich barrier layer that masks structural continuous rovings and stops chemical penetration.
Instant Vinyl Ester Saturation
Absorbs vinyl ester and epoxy resins fast, displacing trapped air to build a solid, pinhole-free barrier.
Heavy-Duty Winding Tension Strength
Pulls smooth under continuous machine roll tension without tearing, wrinkling, or splitting at the edges.

Technical Q&A
Q: What are the essential differences in design logic between this model and conventional/universal models under this category?
A: Standard anti-corrosion tissues (like 30g/m² or 100g/m²) are thin veils designed mainly for smooth cosmetic surface finishes on small parts. SACM450-C is a heavy-duty 450g/m² structural surfacing veil designed specifically for large GRP/FRP chemical storage tanks. It holds up to five times more anti-corrosion resin on the inner tank liner, building a thick, heavy-duty chemical barrier that light veils cannot match.
Q: How should this model be utilized in the actual operation of GRP/FRP storage tanks to achieve optimal performance?
A: Apply SACM450-C as the primary inner corrosion liner directly over your release wax on the mandrel. Saturate the tissue thoroughly with premium vinyl ester resin before winding your structural roving layers. Keep line winding speed steady to allow trapped air to roll out completely before the resin gels.
Q: What are the shelf life and storage limitations after opening the original packaging?
A: Once you open the PE seal, use the roll within 24 hours. In hot, humid tank workshops, exposed glass fibers draw moisture from the air fast. If fiber moisture exceeds 0.15%, resin cross-linking slows down, causing pinholes and liner delamination under chemical loads. Keep unused rolls wrapped tightly in original PE bags.
