Adhesive dispersion test service
The strength is determined by the variance. Visualize quality variations through testing before mass production.
The performance of adhesives greatly depends on the dispersion state of fillers and additives, and even slight differences in dispersion can affect adhesion strength, durability, and appearance quality. Particularly in highly filled systems, issues such as clumping, undispersed particles, and poor mixing due to viscosity increases are likely to occur, leading to variations in dispersion and quality due to sedimentation and separation. These challenges often stem not from the equipment alone but from input conditions, dispersion conditions, and process composition, manifesting as problems that cannot be reproduced during mass production. In this service, we conduct dispersion tests based on the customer's materials and formulation conditions to evaluate the dispersion state, viscosity characteristics, and their impact on adhesive performance. Furthermore, we perform scale-up verification using small machines and pilot equipment to clarify the reproducible conditions for mass production. By conducting thorough verification that delves into process design, we support quality stability and reduction of development time.
