Introduce

In the Philippines, storage tank projects are subjected to long-term environmental stresses caused by high temperatures, high humidity, coastal salt spray, and typhoons.

For industrial storage tanks, potable water tanks, and large-scale modular tanks, the primary challenges lie in ensuring structural stability and reliable corrosion resistance while minimizing maintenance risks over the long term.

As traditional metal tanks are susceptible to damage from humidity and salt spray, fiberglass chopped strand mat has emerged as a vital reinforcement material in tank manufacturing, offering excellent corrosion resistance, strength, and lightweight properties.

Core Challenges in Philippine Tank Repair Projects

Before partnering with us, the Philippine client faced three major pain points in tank repair projects that directly affected project quality and profit margins.

Poor durability of repair layers: Conventional low-weight chopped strand mats had insufficient tensile strength and corrosion resistance. Under the high-temperature, high-humidity climate in the Philippines and long-term immersion in corrosive media, the repair layer often delaminated and leaked again within 1–2 years, leading to rework and customer complaints.
High material waste and slow construction: Standard width mats did not match the size of common tank repair areas. Workers had to cut and splice frequently, resulting in up to 20% material waste and extended construction periods.
Weak bonding on aged tank surfaces: Emulsion-type chopped strand mats had poor adhesion on damp, rusted or residual-contaminated old tank walls. Bubbles and delamination occurred easily during manual lay-up, leading to hidden defects and early failure of the repair layer.

Our Targeted Solutions With 450gsm Powder Chopped Strand Mat

Centered on our 450gsm powder chopped strand mat with 1040mm custom width, we delivered three targeted solutions to address each pain point at the source, optimized for on-site tank repair scenarios.

High 450gsm Weight + Powder Binder for Long-Lasting Repair Strength

To solve the problem of short repair service life, our 450gsm powder chopped strand mat features high fiber content and a premium powder binder system. The 450gsm high basis weight provides sufficient tensile strength and structural reinforcement for the repair layer, effectively resisting medium impact and internal pressure inside tanks.

The powder binder has excellent compatibility with epoxy and vinyl ester resins widely used in tank anti-corrosion, and forms a dense, uniform bonding interface even on aged tank surfaces.

It maintains stable performance under the high-temperature, high-humidity climate in the Philippines, greatly extending the service life of the repair layer and reducing rework costs.

1040mm Custom Width to Cut Waste & Speed Up Construction

Targeted at the size characteristics of tank repair areas, we customized the 1040mm roll width specifically for Philippine tank repair scenarios. This width matches the common size of tank wall repair sections and circumferential weld repair areas, reducing unnecessary cutting and splicing.

It cuts material waste from 20% to less than 7%, and speeds up laying efficiency by more than 30%, helping the client shorten the overall construction cycle and undertake more repair projects within the same period.

Optimized for Hand Lay-Up Repair, Low Porosity & Fewer Defects

Aiming at the characteristics of on-site manual repair construction, our powder chopped strand mat is optimized for hand lay-up processes. The powder binder promotes fast and uniform resin wet-out, effectively reducing trapped air during manual laying.

Fibers are evenly distributed, avoiding thin spots and weak areas, so the finished repair layer has low porosity and excellent compactness. This eliminates hidden defects such as bubbles and delamination, reduces the risk of post-construction leakage, and improves the one-time acceptance rate of repair projects.

Wider Applications Beyond Tank Repair

Besides industrial tank repair, our 450gsm powder chopped strand mat is suitable for a wide range of anti-corrosion and repair scenarios. It can be used for pipeline corrosion repair, FRP ship hull damage repair, chemical equipment lining, cooling tower anti-corrosion, and small FRP product manufacturing.

It adapts to various hand lay-up and spray-up repair processes, and can also be customized with different basis weights and widths according to different project needs.
