How Calcium Carbonate (CaCO₃) Enhances Adhesives & Sealants for the Philippine Market

In recent years, the adhesives & sealants industry in the Philippines has grown significantly due to increasing demand from:

• Residential, commercial, and industrial construction

• Furniture manufacturing (wood, laminate, MDF)

• Packaging and shipping

• Automotive maintenance and industrial manufacturing

One of the most critical raw materials to improve product quality, stability, and cost efficiency is Calcium Carbonate (CaCO₃) powder.

Vietnam, with its high-purity limestone, stable quality, and competitive pricing, is currently the leading supplier for the Philippine market.

Why Calcium Carbonate Is Essential for Adhesives & Sealants

CaCO₃ serves as a primary filler, enhancing both mechanical and chemical properties of adhesives, sealants, and putty products.

 Improved Viscosity and Workability

• Makes adhesives, putty, and sealants easier to apply and spread evenly

• Increases smoothness and reduces clumping

• Ensures smooth and bright surface finish

• Suitable for the hot and humid tropical climate of the Philippines

 Increased Mechanical Strength and Adhesion

• Reduces shrinkage and cracking

• Improves product durability and lifespan

• Stabilizes structure under long-term use in humid conditions

Applications: wall putty, tile adhesive, acrylic sealant, waterproof sealants.

 Structural Stability and Moisture Resistance

• Prevents peeling and sagging

• Ensures long-lasting performance even in outdoor environments

 Cost Reduction

• Using CaCO₃ as a filler reduces the amount of expensive polymers

• Lowers production costs → more competitive pricing

• Enables Philippine manufacturers to scale production without raising raw material expenses

Popular CaCO₃ Grades for Adhesives & Sealants

Selecting the right CaCO₃ grade is crucial for optimal results.

Fine Powder (2–5 Micron)

• Suitable for general adhesives, putty, and wall filler

• Increases smoothness, reduces viscosity

• Ideal for products requiring a smooth and easy-to-apply finish

Ultrafine Powder (1–2 Micron)

• Used for high-performance sealants and waterproofing products

• Improves durability and polymer stability

• Enhances brightness, smoothness, and reduces clumping

Coated CaCO₃ (Stearic Acid or Silane)

• Enhances dispersion and prevents clumping in polymer matrices

• Used in silicone, PU, and acrylic sealants

• Improves adhesion and product longevity

• Carton packaging adhesives

 3. Sealants

• Acrylic, silicone, and PU sealants

• Construction joint sealants

 4. Other Applications

• Industrial adhesive tapes

• Anti-crack and waterproofing adhesives

• Surface protection adhesives for interior woodwork

Why Philippine Manufacturers Prefer Vietnam CaCO₃

 High Purity & Whiteness

• 95–98% whiteness

• Ensures smooth, bright, and high-quality products

  

 Stable Supply & Quality

• Limestone sources in Nghe An and Ha Nam are highly pure and low in impurities

• Consistent quality supports long-term production

 Competitive Pricing

• Export prices lower than China, Malaysia, and India

• Reduces raw material costs for Philippine manufacturers

 Logistics & Delivery

• Fast delivery (5–7 days)

• Supports both jumbo bags and containers for Manila, Cebu, Davao

Case Study – Real Application in Philippine Factories

Factory A in Manila:

• Before: used pure polymer → high cost, uneven surface

• After: added Fine Powder CaCO₃ (3 Micron) from Vietnam

  • Costs reduced by 15–20%

  • Surface smoother, less shrinkage, longer product life

  • Highly rated by construction and interior customers

Factory B in Cebu:

• Used Coated CaCO₃ for PU sealant → improved adhesion and stability under high temperatures

Demonstrates practical benefits of CaCO₃ in adhesives & sealants.

How to Choose the Right CaCO₃ for Your Product

1. Determine the application: adhesive, putty, or sealant

2. Select the right micron size: finer → smoother surface, higher polymer content required

3. Choose coated or uncoated: coated → acrylic/silicone; uncoated → general-purpose products

4. Check whiteness & purity: critical for products requiring bright color

FAQ – Common Questions for Philippine Manufacturers

 Is CaCO₃ environmentally safe?

• Yes, it’s a natural mineral, eco-friendly, and non-toxic.

 How long is the shipping time from Vietnam to the Philippines?

• Typically 5–7 days, depending on the port (Manila, Cebu, Davao).

 How do I decide between Fine Powder and Ultrafine Powder?

• Fine Powder → standard products, easy to apply

• Ultrafine Powder → high-end products requiring smooth finish and durability

 Can CaCO₃ completely replace polymers?

• No, it’s a filler that reduces cost and enhances properties, polymer is still essential for adhesion.

Calcium Carbonate (CaCO₃) is an indispensable material for adhesive and sealant manufacturers in the Philippines because it:

• Enhances durability, smoothness, and moisture resistance

• Improves workability and product stability

• Reduces production costs and increases profit margins

• Provides stable supply and competitive pricing

With high quality, ideal whiteness, and reliable supply, Vietnam CaCO₃ continues to be the top choice for Philippine manufacturers.
