Adhesive

 

Adhesives are important materials used in a wide range of applications, including construction, industry, and DIY. Their quality is directly related to adhesive strength and durability, and proper management is required. In particular, viscosity measurement of adhesives is essential to ensure product consistency and quality. This article explains the types of adhesives, the importance of viscosity measurement, and appropriate management methods.

 

Types of adhesives

There are various types of adhesives depending on their applications and ingredients. Below are some representative ones.

Adhesives for construction and flooring

• Adhesives for flooring (for flooring, carpets, tiles)
• Wallpaper adhesives (glue type, sheet type)
• Waterproof adhesives (for bathrooms and outdoors)
• Mortar adhesives (for repairing concrete and mortar)

 

Adhesives for woodworking and DIY

• Woodworking glue (PVA-based, quick-drying)
• Epoxy adhesives (highly water-resistant and durable)
• Instant adhesives (fast-curing, compatible with a wide range of materials)

 

Adhesives for metal and industrial use

• Metal adhesives (high-temperature resistant, strong adhesion)
• Welding adhesives (used to join metal parts)
• Structural adhesives (used in the automotive and construction fields)

 

Adhesives for plastics and rubber

• Adhesives specifically for plastics (ABS, PVC, polycarbonate, etc.)
• Rubber adhesives (strong adhesion while maintaining flexibility)

 

Adhesives for special purposes

• Heat conductive adhesives (for heat dissipation of electronic components)
• Electrically insulating adhesives (for fixing circuit boards)
• Medical adhesives (for skin, eyelashes, and nails)

 

Importance of viscosity measurement of adhesives

Adhesive viscosity is greatly affected by the manufacturing process and the environment in which it is used, and if not properly managed, the following risks will occur.

 

Deterioration of adhesive performance

Poor adhesion: If the viscosity is too low, the adhesive will not stay in place sufficiently, resulting in insufficient adhesive strength.

Poor curing: If the viscosity is too high, it will not be possible to apply the adhesive evenly, resulting in uneven curing.

 

Deterioration of product quality and occurrence of defective products

Occurrence of peeling and cracking: Adhesive parts will peel off over time due to abnormal viscosity.

Deterioration of durability: Especially for flooring and industrial use, insufficient adhesive strength will shorten the product life.

 

Deterioration of workability

Difficulty in application: If the viscosity is too high, work efficiency will decrease.

Excessive flow/dripping: If the viscosity is too low, it will be difficult to manage during application.

 

Manufacturing and cost problems

Increased material loss: Inappropriate viscosity leads to reapplication and redoing, resulting in unnecessary costs.

Machine problems: Inappropriate viscosity can lead to nozzle clogging and uneven application in automatic application equipment.

 

Regulatory and safety risks

Occurrence of non-standard products: In industrial applications, there is a risk that products that do not meet standards will be shipped.

Possibility of fire and hazardous substances: Inappropriate viscosity management of some adhesives can cause accidents due to the evaporation of hazardous materials or poor curing.

 

Summary

Adhesive viscosity measurement is essential to ensure product consistency and quality. Proper viscosity management maintains adhesive strength and durability, and also leads to optimization and safety in the manufacturing process. Thoroughly measure viscosity as part of your quality control to increase the reliability of your products.

 

RION's viscometer is recommended for measuring viscosity!

RION's viscometer is recommended for the following three reasons.

１．Confidence in accuracy

RION has a long history of manufacturing and developing viscometers. Utilizing our many years of knowledge and experience, we are able to achieve accurate viscosity measurements that are competitive with our competitors.

２．Portable type that can be measured anywhere

Most common viscometers are large and heavy. However, RION's VT-06 is compact and lightweight while maintaining measurement accuracy. The structure is simple, so even people with no knowledge or experience of viscosity measurement can easily measure it.

３．Loved by many customers around the world

RION is a Japanese manufacturer, but the viscometer VT-06 is used not only by customers in Japan but also by customers in countries around the world. VT-06 may be used for quality control in the things you usually use and eat.
