Material Control

Raw Materials Determine a Lot

Using a strict screening method for our suppliers, we can secure high-grade materials for our products such as acrylic resin, 107 glue, lubricating oil, and much more. SANVO always adhered to the mid-high end product quality positioning and is in cooperation with the top three suppliers of industrial materials.

Flow Control

Meticulous Production Process Control

SANVO has detailed operating instructions for the 5 major flow control factors – 5M1E. The Flow Control requires us to filter out unqualified semi-finished products in every subtle link, while Operation Guidelines require us to ensure the production quality in terms of equipment maintenance, material performance management, technical means, and operating conditions.

Details Bring Perfection

Performance and shelf-life are affected by the slightest flaw in our aerosol, adhesive, and waterproofing products. Catching any defects through our detail-oriented QC process ensures our products meet your strict standards.

Testing for Aerosol Products

Drying Time Testing

Paint films are tested for their drying times to determine if they can achieve the desired drying time.

Hardness Testing

The hardness of our paint films is tested for its scratch, wearing, and physical damage resistance.

Adhesion Testing

Using an adhesion test on our paint film ensures they have the desired adhesive performance.

Gloss Test

Checking on the gloss stability of our paint film with the gloss test allows you to satisfy customer demands.

Sealing Diameter Measurement

Guaranteeing the sealing performance of our paint film to prevent leakage is done with our sealing diameter measurement.

Sealing Depth Measurement

Using the sealing depth measurement helps us achieve the preferable sealing depth performance of our spray paints.

Testing for Adhesives & Sealants

External Assessment

QC team members check for any flaws in our adhesive and sealant products such as crusts, bubbles, or pastes.

Density Test

The stability of our adhesive and sealant product’s formula components are checked through our density balance tests.

Surface Drying Time Test

Measuring the average trimming time of our glue with our surface drying time test ensures our adhesive creates a strong bond quickly.

Extrusion Test

The performance of our adhesion and sealant products during construction is checked through our extrusion test.

Tensile Test

We check on the tensile strength of our adhesive and sealant products to determine they can reach optimum adhesive performance.

Testing for Waterproofing & Coating Products

Contrast Ratio Test

Ensure that the production coating film withstands soap and synthetic detergent cleaning to remove surface dust, oil fume and other dirt, while maintaining the original performance

Wash Resistance Test

Checking on the resistance level of our waterproof & coating film with our wash resistance test determines the stability of our products.

Water Permeability Test

Through the water permeability test, we ensure our waterproof & coating film efficiently blocks moisture from passing.

Water Impermeability Test

The leakage-proof performance of our waterproof & coating film is checked through our water impermeability test.

Impermeability Test

Using the impermeability test, we check on our waterproof & coating film to achieve optimum permeation and crystallization rates.

PH Test

Formula stability of our waterproof & coating film is determined through PH testing.
