The official eligibility profile emphasizes that this product must be applied exclusively to intact skin, and use is restricted in any situation that would promote excessive systemic absorption of the alcoholic solvent base.

The interaction profile for Mastisol Liquid Adhesive is structured around constraints related to its physical form and component materials, as regulatory documents do not document systemic pharmacokinetic interactions involving metabolic enzymes or transporters.

Physical and Environmental Constraints

The product’s solvent base contains specially denatured alcohol, which results in its official classification as a flammable liquid and vapor. Regulatory guidelines mandate a strict procedural restriction against co-presence with heat, sparks, open flames, or hot surfaces. Mandatory timing separation from all ignition sources is required during application and until the volatile solvent has fully evaporated to mitigate this environmental hazard.

Substance and Component Interactions

A population-specific restriction is officially noted concerning the product's active ingredients, the natural resins Gum Mastic and Storax. The product is restricted from use in patients with a known hypersensitivity or allergy to these components. Conversely, official documentation affirms the product's crucial clinical compatibility with Chlorhexidine Gluconate (CHG) preparations, ensuring that co-application does not compromise the function of the antiseptic. Furthermore, specialized adhesive removers are required as a necessary procedural substance to safely reverse the product’s long-lasting cohesive effect.

1. Surface Preparation and Micro-Contour Adherence

This initial physical mechanism involves the alcoholic solvent acting on the skin's surface, temporarily degreasing the Stratum Corneum and altering its surface energy. This process is critical because it ensures the maximum wetting and comprehensive contact of the resins with the skin's microscopic crevices, a necessary precondition for forming a final cohesive bond.

---

2. Film Formation and Cohesive Strength

The core action is a rapid chemical cascade where the fast evaporation of the solvent instantly precipitates the natural Gum Mastic and Storax resins. The resins cure into a thin, water-insoluble polymer film, where the Gum Mastic provides quick initial tack and the Storax contributes high internal cohesive strength and resistance to rupture.

---

3. Biomechanical Resilience and Resistance to Dynamic Stress

This domain defines the resulting physical effect: the cured film acts as a mechanical reinforcement, significantly increasing the Peel Adhesion Strength and Dynamic Shear Strength of the secured device. By creating an occlusive barrier, the mechanism ensures the bond retains high mechanical strength against physiological challenges like transepidermal moisture and movement, contributing to sustained mechanical securement of the external device.
